a broad blade 22, engaging the several pumppistons 14, which are suitably notched for the reception of the said blade, and which latter extends through openings 38,- formed in the upper portions of the pump-cylinders 13. In their backward or filling movements the pistons 1e retreat far enough so that the cylinders of the pumps may be filled by the oil in the reservoir passing i'nto said cylinders through the openings just referred to. Bearing against the bell-crank lever 21 is a stiff spring 23, which imparts quick oil forcing or feedingv movements to the pump-pistons 1i when'the short arm of the bell-crank lever 21 falls oii from the high point of the scroll-cam 16 into the low part or notch thereof. From this it results that While the suction or filling movements imparted to the pump-pistons 14 from the scroll-cam 16 through the lever 21 will be comparatively slow and will be variable according to the varying speed at which the engine or motor to be lubricated may be running the oil-forcing or oil-feeding movements imparted to said pistons from said. spring will always be rapid and constant, so that an efcient oil-forcing operation always results therefrom.

The outlet of each of th lpump-,cylinders is I providedwith a spring-pressed ball-valve 211,

which is'inserted in place from the outer end of the tube forming the pump-cylinder, the opening at the outer end of said cylinder being closed by a plug-screw 25, formed partly hollow for the reception of a spring26,wliieh forces 'the bali 2d to its seat. r'he pistons 14C are inserted 'in the chambers of the pumpcylinders 13 from the ends of said cylinders opposite that at which the-ball valves are located, and the openings through which said pistons are inserted are closed by plug-screws 27.

'Each of the delivery-tubes 28 is preferably provided'with a glass tube 29, inserted therein, the said tubes 28 being provided with openings affording windows, and through which windows it can be ascertained at all times whether or not all of the. pumps are properly working. Communicating with each of the said clelivei"},-tubes 28 is a feed-rupe or oil-conducting tube 33, which is to be connected in any suitable manner 'to a portion of the engine or motor to be lubricated.

FromV the foregoing it will be apparent that this invention provides a compact and eiif, cient multiple pump power oiling device, which may bc located in any suitable or convenient relation to the machine or motor to be lubricated and the various delivery-tubes of which may be connected with the parts to 'be oiled, so that an unfailing supply of oil will be automatically delivered to said parts.

Y 1f the multiple-pump oil-feeder be located on the dashboard of an automobile, c working of 'the pumps can be con readers observed through the several sight-feed openings while'the car is running or without 're-'- quiring the occupants to dismount, and owing to the fact that the I pump-operating devices are inclosed within the oil-reservoir they willv themselves be at all times suitably lubricated,

The reservoir 12 is provided with a nozzle or nipple .30, through which oil can' be supplied thereto, andr for long trips it will be advisable to connect the supply-opening of the said reservoir with a larger reservoir, as 31, connected with thereservoir 12 by a pipe 32. Having thus described our invention, We claim and desire to secure by Letters Patent- 1. A power-oiler comprising the combination With an oil-reservoir, of a plurality of4 foice-purnpshaving reciprocating pistons, a

scroll-cam for effecting the suction or filling movements of said pistons, a .lever actuatedfrom said cam and connected with said pistons,

and a spring acting on said lever and serving to impart quick oil forcing or feeding movements to said pistons when the high part of said cam passes the contiguous part of said lever and the latter falls into the notch or low part of said cam. y

2. A power-oiler comprising the combination with the reservoir 12, of a series of pumpcylinders 13 in the lower part thereof, a. piston 14 for cach of said pumps, the bell-crank lever 21 engaging said cam and said pistons, and the cooperating spring 23 for imparting movements to saidv lever in opposition to those effected by said cam.

3. A power-oiler comprising the combina` ntion with the reservoir 12, of a plurality or series of pump-cylinders 13 in the lower portion of said reservoir, a reciprocating piston 1d for each of said pumps, said pistons being notched in their upper sides, the shaft 15, the cam 16 on said shaft, the bell-crank lever 21 one arm of which engages said cam and the other arm of which is constructed to form the blade 22 entering the notches formed in said cylinders, and the spring 23 cooperating with said cam and lever. A

f1. A powcr-oiler comprising the combination with the reservoir 12, of a series of pumpcylinders at the lower part of said reservoir and having openingsV in their upper parts for the entrance of oil, pistons movable in cylinders,'ineans within said reservoir for operating said pistons, spring-pressed ball-valves controlling the outlets from the said pumpcylinders, plug-screws closing the chambers in which the said ball-valves are located, and plug-screws closing the penings to said cylinders through which the said pistons are inserted.
